The promise of mesenchymal stem cells (MSCs) to heal heart disease could be around the corner thanks to a new delivery method tested by regenerative medicine company Cynata Therapeutics Ltd.

Regenerative medicine company Mesoblast Ltd. received an early Christmas present from the FDA for approval of its allogeneic bone marrow-derived mesenchymal stromal cell (MSC) therapy, Ryoncil (remestemcel-L), for steroid-refractory acute graft-vs.-host disease (SR-aGvHD) in children 2 months and older, including adolescents.

Researchers from EMD Serono Research and Development Institute Inc. hypothesized that modulation of two T-cell costimulatory pathways, such as CD28 and OX40, in one single molecule would be more efficient at controlling T-cell activation than modulating each pathway separately.
Tr1x Inc. announced a $75 million series A financing to advance universal allogeneic regulatory T (Treg) and chimeric antigen receptor (CAR)-Treg cell therapies into the clinic to treat autoimmune and inflammatory diseases.
Regenerative medicine company Mesoblast Ltd.’s stock sank nearly 57% on the news that it received a second U.S. FDA complete response letter (CRL) following the resubmission of its BLA for allogeneic stem cell treatment remestemcel-L in children with steroid-refractory acute graft-vs.-host disease. In the CRL, issued a few days after the Aug. 2 PDUFA date, the agency said it requires more data to support approval.

Avoidance of graft-vs.-host disease (GVHD) after a hematopoietic stem cell transplant could depend on certain members of the microbiome. According to a study led by scientists at the Fred Hutchinson Cancer Center (FHCC), while some species of intestinal bacteria repressed the expression of the major histocompatibility complex II (MHC-II), others induced it and triggered the immune response that produces GVHD.
A single low-dose injection with anti-DLL4 in a nonhuman primate model of acute graft-vs.-host disease (aGVHD) dramatically improved post-transplant survival, providing durable protection from otherwise lethal gastrointestinal GVHD, researchers reported in the June 28, 2023, issue of Science Translational Medicine. Blocking DLL4 specifically increased the migration of beneficial regulatory T cells into the intestines, with concomitant reduction in effector T cells, which are the main culprits in aGVHD. Ultimately, these activities effectively provided protection against T-cell-mediated damage in a nonhuman macaque primate model.
